Best Email + SMS Combo Marketing Platforms for 2026
Bottom line up front
For e-commerce stores wanting unified email + SMS at scale, Klaviyo is the structural answer — same dashboard, same customer profiles, native cross-channel orchestration. ActiveCampaign Plus+ is the mid-market alternative. Brevo is the SMB pick combining email + SMS + transactional. For specialist SMS depth alongside Klaviyo email, Postscript + Klaviyo is the two-vendor specialist play. The unified Klaviyo path is simpler and cheaper under 100K SMS sends/month.
Why unified email + SMS matters
Three structural reasons to combine email and SMS in one platform. (1) Unified profiles: a customer's complete engagement history (email opens, SMS replies, abandoned carts, purchases) lives in one subscriber record, segmentable together. (2) Cross-channel orchestration: a campaign sends email first, then SMS to non-openers 48 hours later — automated, not manual. (3) Attribution: revenue attributed to the specific email + SMS sequence that drove conversion, not split across two vendor dashboards.
Running email and SMS separately means manual reconciliation, inconsistent segmentation, and lost cross-channel insight. The combined-platform approach delivers all three benefits at the cost of slightly more complex per-platform tooling. For most e-commerce stores, the trade-off favors combined.
How we picked
Five criteria. (1) Email and SMS in one platform with shared subscriber records. (2) Cross-channel automation orchestration (email → wait → SMS). (3) Unified attribution dashboard. (4) TCPA-compliant SMS opt-in flow separate from email opt-in. (5) Reasonable combined pricing. Every pick clears 4 of 5; only Klaviyo, Brevo, and Sendlane clear all 5 with depth.

1. Klaviyo (email + SMS) — e-commerce default
Best for: E-commerce stores at scale wanting unified email + SMS in one platform.
Klaviyo's unified email + SMS is the structural answer for e-commerce. Same dashboard, same subscriber profiles, native cross-channel automation flows (welcome series with email + SMS touches, abandoned-cart with email then SMS reminder), unified attribution. Pricing scales with subscriber count for email; SMS is per-message ($0.01-$0.03 per SMS in US).
Pros: Best unified e-commerce platform; native orchestration; mature attribution.
Cons: Pricing scales fast at higher subscribers; less specialist SMS depth than Postscript.
2. ActiveCampaign Plus+ — mid-market automation
Best for: Mid-market marketing automation with email + SMS combined.
ActiveCampaign Plus+ tier ($70/mo+ for 1K contacts) bundles SMS alongside email with unified automation. Cross-channel flows configured once, fired across both channels.
3. Brevo — SMB combined
Best for: SMB operators wanting email + SMS + transactional in one platform at affordable price.
Brevo bundles email, SMS, and transactional email in one platform. Send-volume-based pricing rather than subscriber-based, which can be cheaper at higher subscriber counts.
4. Postscript + Klaviyo — specialist SMS depth
Best for: Stores with high SMS volume (100K+ sends/month) wanting specialist SMS depth alongside Klaviyo email.
Postscript is the SMS specialist for Shopify; combined with Klaviyo email via integration, you get best-of-breed in both. Two vendors instead of one, but the SMS depth is real for high-volume operations.
5. Yotpo (Loyalty + Reviews + SMS) — Yotpo customers
Best for: Yotpo customers running reviews and loyalty wanting unified SMS.
Yotpo bundles SMS with their broader stack (reviews, loyalty, subscriptions). Unified Yotpo dashboard for cross-product orchestration.
6. Sendlane — DTC at lower cost
Best for: DTC brands wanting unified email + SMS at lower cost than Klaviyo.
Sendlane positions as a Klaviyo alternative for DTC brands — unified email + SMS, cleaner UI, lower pricing at typical DTC scale ($99-$500/mo subscriber-based).

Frequently asked
Why combine email and SMS in one platform?
Three reasons. (1) Unified profiles: a customer's email engagement and SMS engagement should live in one record, segmentable together. (2) Cross-channel orchestration: a campaign can fire email first, then SMS to non-openers 48 hours later. (3) Attribution: revenue attributed to specific touches across both channels. Running email and SMS separately means manual reconciliation, inconsistent segmentation, and lost cross-channel insight.
Which platform has the best unified email + SMS?
Klaviyo bundles email + SMS in one platform with unified profiles, segmentation, and attribution — the depth pick. ActiveCampaign Plus and higher includes SMS alongside email. Brevo (formerly Sendinblue) bundles email + SMS + transactional in their full suite. For specialist SMS depth alongside Klaviyo email, Postscript + Klaviyo via integration is common but two vendors. The unified Klaviyo bundle is structurally simpler.
How much does email + SMS combined typically cost?
Klaviyo bundled email + SMS: $20-$1,700/mo subscriber-based pricing for email; SMS pricing varies by send volume ($0.01-$0.03 per SMS in US). For a 5,000-subscriber store sending 4 emails/month and 4 SMS/month: ~$45/mo Klaviyo email + ~$200/mo Klaviyo SMS = $245/mo combined. Compared to Klaviyo email + Postscript SMS ($45 + $100 minimum = $145/mo), the standalone SMS specialist is cheaper but split across two vendors.
Should I send the same content via email and SMS?
No. Email and SMS have different conventions. Email: longer-form, branded design, multiple links, footer with unsubscribe. SMS: short, direct, single CTA, "Reply STOP to opt out." A campaign typically sends a long email to engaged subscribers, then a short SMS reminder to non-openers 48-72 hours later with the key offer condensed. Cross-channel orchestration platforms make this easy; separate vendors make it manual.
How does TCPA compliance work in combined platforms?
SMS opt-in is separate from email opt-in — a customer who opted into email has not opted into SMS. Combined platforms handle this with separate consent tracking — Klaviyo and Brevo both maintain separate email-opt-in and SMS-opt-in flags per subscriber, and segments respect both. TCPA-compliant SMS sends require explicit SMS opt-in, double-opt-in confirmation, STOP-keyword response, and time-of-day restrictions.
When should I prefer Klaviyo + Postscript over unified Klaviyo?
When SMS volume justifies specialist depth. Postscript is built for SMS only — deeper SMS features (deliverability tools, specialty number management, advanced flows). For stores doing 100K+ SMS sends/month or where SMS is 30%+ of email-attributed revenue, Postscript's specialist tooling earns its premium. Below those thresholds, unified Klaviyo is simpler and cheaper.
